CAR ROOF.

Specification of Letters Patent.

Patented June 6,1922.

Application filed April 26, 1920. Serial No. 376,612.

T 0 allot/10172, it may concern Be it known that I, VVALTER P. MURPHY, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have in vented a new and useful Improvement in Car Roofs, of which the following is a specification.

This invention relates principally to car roofs of the corrugated radial type shown in my Patent No. 1,227,484, dated May 22, 1917 wherein corrugated roof sheets extend entirely across the car and are secured at their lapped side margins to the car substructure at the caves and ridge portions thereof.

One of the principal objects ofthe present invention is to provide a simple and efficient means for securing the eaves portions of the sheets to the car substructure, to provide for ventilation at the caves, to provide a weather-proof eaves construction and to facilitate the attachment of the roof parts to the car. The invention consists principally in means for securing the eaves ends of the sheets to the car, and it further consists in the construction and combination of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification, wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a plan view of the eaves portion of a car roof embodying my invention, parts broken away to more clearly illustrate the invention;

Fig. 2 is a side elevation of the eaves portion of the car shown in Fig. 1 with parts broken away to disclose the ends of the sheets and the eaves ends;

Fig. 3 is an enlarged vertical cross section through the eaves portion of the roof on'the line 3-3 in Fig. 2;

Fig. 4 is a cross section similar to Fi r 3 the section being taken through one of the securing bolts on the line 14: in Fig. 2:

Fig. 5 is a fragmentary side view of the eaves portion of the roof in the region o a securing bolt; and

Fig. 6 is a view similar to 3 showin" a modified form of eaves construction.

The present roof comprises rigid load sir taining corrugated metal roof sheets 7 arched transversely of the car and extending y from side plate to side plate with their corv rugations extending cross-wise of the car. The side margins of each sheet overlap the side margins of the adjacent sheet, the corrugations of the respective sheets engaging each other to form seams or joints, the ex v tent of the overlap being preferably two or three corrugations. The eaves ends of the roof sheets are supported on the outwardly extending upper flange of an angle iron eaves strip 8. The eaves strip is arranged longitudinally of the car side with its vertical flange extending down parallel with the outer surface of the side sheathing 9. The caves angle is secured to the outer face of the side sheathing along the upper surface thereof with carriage bolts 10 that extend horizontally through the side sheath ing 9 and the side plate 11. The bolts 1 are provided with nuts on their inner ends. which bear against the inner face of the side plate and hold said bolts in place.

Extending lengthwise of the car, at the eaves thereof, is a combined eaves cap and fame, 12 of angular section which serves as a flashing and retaining member for the eaves ends of the sheets. The upper flange of the eaves cap extends inwardly parallel with the pitch of the roof and overlies the eaves mar g1 nal portion of the sheets The other flange of the eaves strip extends downwardly across the openings formed between the top flange of the eaves angle and the crest of the corrugations to prevent rain and snow from blowing through these openings and entermg the interior of the car. The depending flange of the eaves cap is spaced laterally from the ends of the sheet far enough to form a space to permit air to enter the openings formed by the corrugations for ventilating purposes and to permit rain, snow and cinders to pass off the eaves of the roof. The eaves cap extends across the en tire widthof the eaves ends of the sheets. thereby firmly holding the sheets down at the eaves, and the eaves cap, together with the eaves portions of the lapped side margins of the roof sheets, are firmly secured to the eaves angle 8 by means of bolts 13. These bolts passthroughthe lapped side margins-of the sheets, as well as the eaves cap, and prevent the sheets from pulling out from beneath the top flange of the eaves 14, which are inclined inwardly and downwardly from the depending flange with their free lower ends engaging the upper surface of the eaves angle. These tongues act spacers and prevent the eaves cap from crushing the ends' of the sheets when the nuts of the bolts lg are drawn tight. These tongues also stiffen the eaves cap and prevent sagging of the same and also transmit the pressure caused by tightening the nuts of the s curing bolts directly to the eaves angle, thus relieving the eaves ends of the sheets of this pressure as well as the weight of the eaves cap. The eaves cap may be equipped with two sets of tongues, one adapted to bear on the eaves angle, as shown in Fig. 3, and the other on the sheet, shown in Fig. 6. The tongues 14 which engage the sheets, bear upon the upper surfaces of the valleys of their corrugations, thereby firmly clamping the sheets to the horizontal flange of the eaves angle and also permitting the tongues to act as spacers for holding the upper flange of the eaves cap a predetermined distance from the eaves angle. In Fig. 6,.a slightly modified form of eaves angle 8 is shown, the upper flange of the eaves angle being disposed horizontally instead of being inclined to conform to the pitch of the roof, as shown in Fig. 3, and the securing bolt 13 being shown with its head portion uppermost.

The eaves cap may be provided with any desired number of tongues. For instance. it may be desirable to provide a tongue for every. other corrugation, or, if desired, all of the tongues can be made to bear against either the eaves angle or the sheets.

What I claim is:

1. A car roof comprising roof sheets arranged crosswise of the car and eaves caps secured to the car and covering the eaves ends of said roof sheets, said eaves caps having portions which bear against the car substructure and space the same therefrom, and having integral tongue port-ions which bear against the roof sheets and hold the same down on the car substructure.

2. car roof comprising roof sheets extending crosswise'of the car and connected along. their side margins by joints, acontinuous eaves cap covering the eavesends of said roof sheets, and vertically disposed fasteners securing said cap to the car, said eaves cap extending above the tops of the joints .and having' aplurality of integral tongue portions which engage the sheets between 3. A; car roof comprising roof sheets extending crosswise ofthe car and supported at their. eaves ends on the car substructure, said roof sheets having raised ribs and their adjacent sideymargins overlapped; to cform joints, and an} eaves capextending lengthwise of the car and covering the eaves ends of said roof sheets, said eaves cap being secured to the car substructure and having portions extending into the raised ribs of said sheets, said portions being adapted to bear against the car substructure to space said eaves cap a desired distance above the car substructure.
